Code Description

ICD-10 C79.01 is a billable code used to indicate a diagnosis of secondary malignant neoplasm of right kidney and renal pelvis.

Key Diagnostic Point:

C79.01 refers to the presence of metastatic cancer in the right kidney and renal pelvis, originating from a primary malignancy located elsewhere in the body. This condition indicates that cancer cells have spread to the kidney from another site, which is crucial for treatment planning and prognosis. The right kidney and renal pelvis may be affected by various types of primary cancers, including lung, breast, or colorectal cancers. The diagnosis of a secondary malignant neoplasm often involves imaging studies such as CT scans or MRIs, alongside histopathological confirmation through biopsy. Staging of the disease is essential, as it helps determine the extent of metastasis and guides therapeutic decisions. Palliative care considerations are also vital, focusing on symptom management and improving the quality of life for patients with advanced disease. Given the complexity of metastatic disease, a multidisciplinary approach is often required, involving oncologists, nephrologists, and palliative care specialists.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Determining the primary site of cancer can be challenging.
  • Need for accurate staging to guide treatment.
  • Differentiating between primary and secondary neoplasms.
  • Potential for multiple metastatic sites complicating coding.

Audit Risk Factors

  • Inadequate documentation of the primary cancer site.
  • Failure to document staging information.
  • Misclassification of primary vs. secondary neoplasms.
  • Lack of clarity in pathology reports.
